Influencing of irrigation on the performance of cigar wrapper tobacco (Nicotiana Tabacum L.)

Abstract

The effect of irrigation on the growth performance and wrapper leaves production of the Basuki L2 variety was conducted at the experimental area of PTRTC, Echague, Isabela from January to April, 1987. An RCBD experimental design was setup with six irrigation treatments in which the schedule and amount of irrigation water applied depended on pre-set available soil moisture depletions. One treatment served as a control in which no irrigation was applied. The standard gravimetric method of determining soil moisture content was used while in the estimation of actual evapotranspiration, the water balance equation was used. The overall growth performance of the cigar-wrapper tobacco in all the irrigation treatments was better than those without irrigation (control) at 1% level of significance. Highest total yield and percentage wrapper yield was obtained when irrigation schedule was set at 40% available moisture depletion. However, filler yield in percent was highest for unirrigated tobacco. There was a direct relationship of crop water use to total yield, wrapper yield (%), number of harvested leaves and plane height. On the other hand, specific leaf weight was inversely related to crop water use.
